'15 Claims.

My present invention, which relates to .a threepart ring mold, is concerned particularly with a means for preventing leakage at the joints thereof. Ringmolds of the type commonly used for baking have in the past been subject to leakage at the points of connection between the ends of the ring, and around the edges of the bottomw-hich is fittedinto the ring, .11; is the primary object of my invention to provide a convenient and inexpensive means for preventing any such leakage. The parts which enter into the construction by which these objectives are gained, are simple, inexpensive and .easily assembled. ,A suggestive embodiment of my invention is set forth .in the accompanying draw- .ings, wherein- Figure 1 is a perspective View of the ring mold inits entirety;

The ring mold of my invention is shown best in Figure 1. My ring mold consists principally of an-elongated strip l5,.as .of sheet metal, curved or bent through 360 so as to presentits opposite ends, l6 and I'Lin meeting relation. The upper edge of the strip I5 is outwardly .curled, and disposed therein and secured thereunder is a wire reinforcement l9, coextensive in length with the strip [5. One end of the wire reinforcement l9 protrudes beyond the strip end, and the other end terminates a corresponding distance short of the otherstrip endisee Fig. 4) ,thus

(c1. se e providing a Trecess to accommodate the protruding wire end '20 when theends i6 andill of. the strip IS-arein buttrelation. Q

As here shown, the lower edge '23 of the strip i5 .is curled inwardly slightly fmore than A bottom plate 2d having depending rolled edges 25 'is adapted, when placed within the "ring, to .in'terfit ,its rolled, edges '25 with the inwardly curledlower edge '23 of the strip, thereby ".providing an easily removable, leak-proof bottom for the ring mold. A j

The ends 16 and '11 of the strip l'JJIare provided with flanges 26 and 21, respectively, .out- ,wardly and reversely bent and enten'ding from a point near the upper edge l8 of the strip. toward the lower edge .23, but terminating. short of the, latter. The "lower ends of 'eachflange slant outwardly as at 28 so as to aid in guiding the clip, presently to be described, over the flanges.

A tongue 29 extends laterally from one end, here indicatedas the. end [1, ot the strip in the region adjacent its lower edge 23, andbelow the flange 21. This tongue is adaptedior overlap with the opposite stripend I51, when the two strip ends are otherwis'e in butt relation. By means of this overlapping connectionlbetween the two :ends I prevent the leakage whichmight otherwise occur at the joining ends ofthe strip.

A hollow spring clip Cis adapted to form a releasable interlock between the two strip: ends 1.6 and 'l'l.v This clip as shown in Figs. 3 and 5 comprises :an elongated strap 3! of sheet metal formed with sides '32, and over the greater part of its length with inner walls 36 and?! separated from each other and from the strap 31 so as to provide a channel. wherein th oppositely extended flanges '26 and, 21 are adapted to be slidingly received. The inner walls iii and 3-1 are approximately. coextensive in length with the flanges 26 and .Zl. The portion of the clip which lies below the flanges is 'formed. to provide a' .hollowlpocket defined'bythe sides 32and the strap which is inwardly curved at its lower end. This pocket is adapted to catch any doughor like material which may pass through the joint, thereby preventing any spilling or leaking. The clip near its upper end is provided with a trans verse outset channel 38 wherein the reinforced upper edge l8 of the 's'tripis adapted to be received. I thereby form a spring lock which, being resilient enough to yield and permit movement of the reinforced upper edge I8 into or out of the channel, yet tending when so positioned to maintain itself fixedly in place, snaps tightly over the upper edge of the strip when the clip is applied to the ring mold.

The upper end of the clip may terminate in an outwardly extending tab 39 convenient for manipulation. As here shown, the clip is formed 5 in its upper region with an outwardly projecting rib 40 extending lengthwise of the clip to provide a reinforcement for the spring lock. The lower end 4| of the clip is curled inwardly and then upwardly, and is adapted to fit snugly against the joint between the strip ends and to extend lengthwise along the inward curl of the lowerv edge 23 of the strip I5. This curve may" be likewise reinforced as by alongitudinallyextending rib 42 disposed in' the lowerregion of the clip.

The clip is properly positioned bysliding it upwardly over the flanges 26 and 21 until the curl 4| at the lower end of the clip is tight against the lower edge of the strip l5, and the spring lock of the clip is snapped over the upper edge l8 of the strip. When the clip is in place my ring mold is complete, and there is no possibility of leakage through any of the joints. In Fig. 8 I show a slightly modifiedconstruc- 25 tion. The strip ends are here formed with tongues 29 (in dotted lines) and 30, adapted to interfit when the ring ends arecotherwise in butt relation. As here shown the tongue 29 is fitted Within the tongue 30. 30

A modified form of my invention is shown in Figs..9-12. The lower end 43 of theclipstrap 3| is inset and adapted when the clip is in place to directly engage the exterior surface of the mold. A longitudinal, inwardly projecting rib 44 is formed centrally of the clip lower end which is desirably. inwardly curled at 45 through 90 or more. This rib serves the dual purpose of reinforcing the clip, and of fitting into a slot 45 m which mayintervene between the strip ends in 40 the lower region of the mold, the rib then acting as a closure therefor to prevent leakage therethrough.

The present ring releasable interlock for the two ends of the mold is held in place by its own spring action, and consequently requires no aid from any 'tool when it is applied or removed. It may be made of lightweight sheetmetal, and still be amply, strong to fulfill the requirements for which it is designed due, in part, to the provisionof the embossed reinforcements which extend longitudinally thereof in each end region to provide theneeded strength. This clip, while serving conveniently as a releasable lock for thecmold ends, also acts to prevent the leakage of dough or other contents which may be expressed from the mold-during the process of baking. Thlsis an important consideration because it conends is also considerably improved by the overlapping tongueor tongues at the point wherethe leakage problem is usually. most serious. The locking clip serves to maintain the meeting ends of the mold in their closed relation, and in addi-;,-

,tion offers an exterior closed chamber, in its lower end, into which spilled dough may possibly escape in case ,of leakage. .If .it be preferred not'to employ one or more laterally extending mold has advantages from g several standpoints. The clip which provides the 45 reinforced rib at the lower end of the clip will serve efl'ectively as a closure to prevent the escape of the contents from the mold.

In use, the mold may be readily disassembled by first removing the clip which frees the mold ends for separation, the bottom then disengaging of its own accord. Each of these parts is then free for individual handling and cleaning, and no difficulty will be encountered in removing any spilled dough which may possibly have collected on the inside of the clip or in the joint between I the two ends of the mold. Accordingly, by the I improved features of this construction, the mold may be maintained in a perfectly sanitary condition, and in caseof damage to any of its parts the substitution of a new, fresh part will involve 1 no diificulty whatsoever.
